Supernatural
star Jensen Ackles is one proud papa, and he took to Instagram to
celebrate his daughter's birthday. The CW actor posted an adorable photo
honoring his first child, daughter J.J., who forever changed his life
four years ago.

The first child of Jensen and his wife, Danneel Ackles, Justice Jay (aka J.J.) was born on May 30, 2013, a little over three years after the couple married. In December 2016, J.J. got two new siblings when Jensen's twins, Arrow and Zeppelin, were born.

It's a doubly special day for Supernatural fans because J.J. Ackles shares a birthday with Mark Sheppard, who played Crowley the King of Hell. Of course he's almost 40 years older than her, turning 53.
